Description

With this function you can decode a base64 encoded string
(created using the buffer_base64_encode()
function) into a buffer. Unlike the function buffer_base64_decode(),
this will not create a buffer for you, but rather you should
already have created the buffer (see buffer_create), the id of which
you would then use with this function. The "offset" is the position
within the buffer to decode the given string (in bytes).

Example:

The above code will create a buffer and store the unique id for
it in the variable "buff", then open an ini file and read a string
from it into the local variable "str". This string is then decoded
into the newly created buffer before closing the ini file
again.
